Summary

This study addresses the lack of standardized warrants for Major Traffic Generator (MTG) guide signing in Texas. MTGs are regional attractions, such as stadiums or parks, that draw visitors from beyond local communities. While the Texas Manual on Uniform Traffic Control Devices (TMUTCD) defines criteria for regular traffic generators, it lacks specific guidelines for MTGs. Existing standards from other states, such as Minnesota, Missouri, and North Carolina, are not directly applicable to Texas due to differing geographical and demographic characteristics. The research aims to establish eligibility criteria and design specifications for MTG guide signs suitable for the Texas environment. The methodology involved a comprehensive review of literature and signing practices in other states, supplemented by surveys of transportation engineers, MTG executives, and motorists. To synthesize the qualitative expert opinions and varying state standards into quantifiable criteria, the researchers developed a fuzzy logic–based algorithm. This approach processed input variables including minimum parking spaces, maximum distance from highways, annual attendance, and event frequency. Preliminary recommendations for symbol types, sign locations, and sizes were derived from survey feedback and literature. These designs were then validated through driving simulator tests and computer slide shows to assess driver recognition and comprehension. The study found that engineers and MTG stakeholders strongly support the use of guide signs for MTGs, with 88% of surveyed motorists deeming them necessary. Engineers preferred category-oriented symbols and placing plaques on top of parent guide signs, with a minimum text size of 6 inches. The fuzzy logic synthesis of manual criteria and engineer opinions resulted in specific eligibility warrants for Texas. These criteria require a minimum of 1,000 parking spaces and annual attendance thresholds ranging from 200,000 in rural areas to 300,000 in metropolitan areas. Additionally, MTGs must be located within 2 miles of a highway in urban/suburban areas or within 6 miles in rural areas. Simulator tests confirmed that specific symbol designs and placements effectively aided driver recognition. The significance of this work lies in providing the Texas Department of Transportation with a data-driven framework for MTG guide signing. By establishing clear, synthesized warrants, the study enables consistent identification of eligible facilities and standardizes the design of guide signs. This improves navigation for unfamiliar motorists and ensures that signing resources are allocated to facilities with sufficient regional appeal and traffic generation, addressing a critical gap in Texas traffic control standards.

Key finding

The study established finalized eligibility criteria for Texas MTGs requiring a minimum of 1,000 parking spaces, location within 6 miles of a rural highway or 2 miles of an urban highway, and annual attendance of at least 200,000 to 300,000 visitors depending on population density.
